Nine gas transmission system operators (TSOs) around the Baltic Sea have signed a Memorandum of Understanding (MoU) to work together in developing hydrogen infrastructure and fostering the hydrogen market in the region. The collaboration involves companies from countries like Poland, Estonia, Denmark, Finland, Lithuania, Sweden, Germany, and Latvia. The goal is to coordinate activities for the development of the hydrogen economy, including transmission and storage infrastructure projects. The Baltic Sea region, known for its renewable energy resources, aims to leverage its potential to produce clean hydrogen and establish a hydrogen market. The TSOs are aligning their efforts with the EU's Baltic energy market interconnection plan (BEMIP) group. Projects like the Nordic-Baltic Hydrogen Corridor are set to contribute to achieving the REPowerEU plan targets. By working together, the TSOs hope to create a competitive and liquid hydrogen market that supports the EU's climate goals and energy system resilience.
